CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to U.S. Provisional Patent Application No. 62/695,437, filed Jul. 9, 2018, which is hereby incorporated by reference in its entirety.

FIELD OF THE DISCLOSURE

The disclosure relates to the field of plant breeding and, more specifically, to melon variety NUN 16108 MEM. The disclosure further relates to vegetative reproductions of melon variety NUN 16108 MEM, methods for tissue culture of melon variety NUN 16108 MEM and regenerating a plant from such a tissue culture and to phenotypic variants of melon variety NUN 16108 MEM.

BACKGROUND OF THE DISCLOSURE

The goal of plant breeding is to combine various desirable traits in a single variety or hybrid. Such desirable traits may include greater yield, resistance to diseases, insects or other pests, tolerance to heat and drought, better agronomic quality, higher nutritional value, enhanced growth rate, and improved fruit properties.

Breeding techniques take advantage of a plant's method of pollination. There are two general methods of pollination: a plant self-pollinates if pollen from one flower is transferred to the same or another flower of the same genotype. A plant cross-pollinates if pollen comes to it from a flower of a different genotype. Plants that have been self-pollinated and selected for (uniform) type over many generations become homozygous at almost all gene loci and produce a uniform population of true breeding progeny of homozygous plants. A cross between two such homozygous plants of different lines produces a uniform population of hybrid plants that are heterozygous for many gene loci. The extent of heterozygosity in the hybrid is a function of the genetic distance between the parents. Conversely, a cross of two plants each heterozygous at a number of loci produces a segregating population of hybrid plants that differ genetically and are not uniform. The resulting non-uniformity makes performance unpredictable.

The development of uniform varieties requires the development of homozygous inbred plants, the crossing of these inbred plants to make hybrids, and the evaluation of the hybrids resulting from the crosses. Pedigree breeding and recurrent selection are examples of breeding methods that have been used to develop inbred plants from breeding populations. Those breeding methods combine the genetic backgrounds from two or more plants or various other broad-based sources into breeding pools from which new lines are developed by selfing and selection of desired phenotypes. The new plants are evaluated to determine which have commercial potential.

One crop species which has been subject to such breeding programs and is of particular value is the melon. It belongs to the Cucurbitacea family and has originated in Asia. The plant is a large and sprawling annual, grown for its fruit.

The fruit of most species of Cucumis melo is often colored attractively, commonly yellow, orange or red. Melon can contain black seeds, which are considered undesirable for some uses. Common types include Persian, Honey Dew, Casaba, Crenshaw, Common/Summer and subtypes such as the popular Galia, Canary, Western Shipper or the new Crispy types. Melon is typically consumed fresh as desserts, snacks, or in salads.

One of the leading consumers of melon is the United States with California as the major producer. Melon is available year-round but supply peaks in August and ends in November.

While breeding efforts to date have provided a number of useful melon varieties with beneficial traits, there remains a great need in the art for new varieties with further improved traits. Such plants would benefit farmers and consumers alike by improving crop yields and/or quality. Breeding objectives include varying the color, size, texture and flavor of the fruit, absence of seeds, optimizing flesh thickness, disease or pest resistance, yield, suitability to various climatic circumstances, solid content (% dry matter), sugar content, and storage properties.

DEFINITIONS

“Melon” or “muskmelon” refers herein to plants of the species Cucumis melo, and fruits thereof. The most commonly eaten part of a melon is the fruit or berry, also known as pepo. The fruit comprises exocarp, mesocarp, endocarp or seed cavity, hypanthium tissue and optionally seed. Exocarp, mesocarp, endocarp or seed cavity, hypanthium tissue, and seed coat of the seed are maternal tissues, so they are genetically identical to the plant on which they grow.

“Cultivated melon” refers to plants of Cucumis melo (e.g., varieties, breeding lines or cultivars of the species C. melo), cultivated by humans and having good agronomic characteristics.

“Cantaloupe melon” refers to orange-fleshed melons.

Likewise, “UPOV methods” to determine specific parameters for the characterization of melon are described at upov.int.

“RHS” or “RHS color chart” refers to the color chart of the Royal Horticultural Society (UK), which publishes a botanical color chart quantitatively identifying colors by a defined numbering system. The chart may be purchased from Royal Horticulture Society Enterprise Ltd. RHS Garden; Wisley, Woking; Surrey GU236QB, UK, e.g., the RHS color chart 2007.

“Plant part” includes any part of a plant, such as a plant organ (e.g., harvested or non-harvested fruits), a plant cell, a plant protoplast, a plant cell tissue culture or a tissue culture from which a whole plant can be regenerated, a plant cell that is intact in a plant, a clone, a micropropagation, plant callus, a plant cell clump, a plant transplant, a vegetative propagation, a seedling, a fruit, a harvested fruit, a part of a fruit, a leaf, a part of a leaf, pollen, an ovule, an embryo, a petiole, a shoot or a part thereof, a stem or a part thereof, a root or a part thereof, a root tip, a cutting, a seed, a part of a seed, hypocotyl, cotyledon, a scion, a graft, a stock, a rootstock, a pistil, an anther, and a flower or parts of any of these and the like. Seed can be mature or immature. Pollen or ovules may be viable or non-viable. Also, any developmental stage is included, such as seedlings, cuttings prior or after rooting, mature plants or leaves. Alternatively, a plant part may also include a plant seed which comprises maternal tissues of melon variety NUN 16108 MEM and an embryo having one or two sets of chromosomes derived from the parent plant, e.g., from melon variety NUN 16108 MEM. Such an embryo comprises two sets of chromosomes derived from melon variety NUN 16108 MEM, if it is produced from self-pollination of said variety, while an embryo derived from cross-fertilization of melon variety NUN 16108 MEM, will comprise only one set of chromosomes from said variety.

“Reference Variety for NUN 16108 MEM” refers herein to variety NUN 26191 MEM, which has been planted in a trial together with melon variety NUN 16108 MEM. The characteristics of melon variety NUN 16108 MEM were compared to the characteristics of the Reference Variety as shown in Tables 1 and 2. The distinguishing characteristics between melon variety NUN 16108 MEM and the Reference Variety are shown in Table 3.

“Rootstock” or “stock” refers to the plant selected for its root system, in particular for the resistance of the roots to diseases or stress (e.g., heat, cold, salinity etc.). Generally, the quality of the fruit of the plant providing the rootstock is less important.

“Scion” refers to a part of the plant attached to the rootstock. This plant is selected for its stems, leaves, flowers, or fruits. The scion contains the desired genes to be duplicated in future production by the stock/scion plant and may produce the desired melon fruit.

“Stock/scion” or “grafted plant” refers to a melon plant comprising a rootstock from one plant grafted to a scion from another plant.

“Harvest maturity” is referred to as the stage at which a melon fruit is ripe or ready for harvest or the optimal time to harvest the fruit for the market, for processing or for consumption. In one aspect, harvest maturity is the stage which allows proper completion of the normal ripening.

“Flavor” refers to the sensory impression of a food or other substance, especially a melon fruit or fruit part (fruit flesh) and is determined mainly by the chemical senses of taste and smell. Flavor is influenced by texture properties and by volatile and/or non-volatile chemical components (organic acids, lipids, carbohydrates, salts etc.).

“Aroma” refers to smell (or odor) characteristics of melon fruits or fruit parts (fruit flesh).

“Harvested plant material” refers herein to plant parts (e.g., fruits detached from the whole plant), which have been collected for further storage and/or further use.

“Yield” means the total weight of all melon fruits harvested per hectare of a particular line or variety. It is understood that “yield” expressed as weight of all melon fruits harvested per hectare can be obtained by multiplying the number of plants per hectare times the “yield per plant”.

“Marketable yield” means the total weight of all marketable melon fruits, especially fruit which is not cracked, damaged or diseased, harvested per hectare of a particular line or variety. A “marketable fruit” is a fruit that has commercial value.

A plant having “all the physiological and morphological characteristics” of a referred-to-plant means a plant showing the physiological and morphological characteristics of the referred-to-plant when grown under the same environmental conditions, preferably in the same experiment; the referred-to-plant can be a plant from which it was derived, e.g., the progeny plant, the progenitor plant, the parent, the recurrent parent, the plant used for tissue- or cell culture, etc. A physiological or morphological characteristic can be a numerical characteristic or a non-numerical characteristic. In one aspect, a plant has “all but one, two or three of the physiological and morphological characteristics” of a referred-to-plant, or “all the physiological and morphological characteristics” of Tables 1 and 2 or “all or all but one, two or three of the physiological and morphological characteristics” of Tables 1 and 2.

The physiological and/or morphological characteristics mentioned above are commonly evaluated at significance levels of 1%, 5% or 10% if they are numerical (quantitative), or for having an identical degree (or type) if not numerical (not quantitative), if measured under the same environmental conditions. For example, a progeny plant or a Single Locus Converted plant or a mutated plant of variety NUN 16108 MEM, may have one or more (or all) of the essential physiological and/or morphological characteristics of said variety listed in Tables 1 and 2, as determined at the 5% significance level (i.e., p<0.05), when grown under the same environmental conditions.

“Distinguishing characteristics” or “distinguishing morphological and/or physiological characteristics” refers herein to the characteristics which distinguish the new variety from other melon varieties, such as the Reference Variety (i.e., are different), when grown under the same environmental conditions. The distinguishing characteristics between melon variety NUN 16108 MEM and its Reference Variety are described herein and can be seen in Table 3. When comparing melon variety NUN 16108 MEM to other varieties, the distinguishing characteristics may be different. In one aspect, the distinguishing characteristics may therefore include one, two, three or more (or all) of the characteristics listed in Tables 1 and 2. All numerical distinguishing characteristics are statistically significantly different at p<0.05 between melon variety NUN 16108 MEM and the other variety (e.g., the Reference Variety).

Melon variety NUN 16108 MEM has the following distinguishing characteristics when compared to the Reference Variety as shown in Table 3: 1) ______; 2) ______; 3) ______; 4) ______; 5) ______; 6) ______; 7) ______; and 8) ______, when grown under the same environmental conditions.

Thus, a melon plant “comprising the distinguishing characteristics of melon variety NUN 16108 MEM” (such as a progeny plant) refers herein to a plant which does not differ significantly from said variety in the distinguishing characteristics above. Therefore, in one aspect, the disclosure provides a plant which does not differ significantly from melon variety NUN 16108 MEM in the distinguishing characteristics above.

Similarity and differences between two different plant lines or varieties can be determined by comparing the number of morphological and/or physiological characteristics that are the same (i.e., statistically not significantly different) or that are different (i.e., statistically significantly different) between the two plant lines or varieties using plants grown under the same environmental conditions. A numerical characteristic is considered to be “the same” when the value for a numeric characteristic is not significantly different at the 1% (p<0.01) or 5% (p<0.05) significance level, using one way analysis of variance (ANOVA), a standard method known to the skilled person. Non-numerical or “degree” or “type” characteristic is considered “the same” when the values have the same “degree” or “type” when scored using USDA and/or UPOV descriptors, if the plants are grown under the same environmental conditions.

A “plant line” is, for example, a breeding line which can be used to develop one or more varieties. A breeding line is typically highly homozygous.

“Hybrid variety” or “F1 hybrid” refers to the seeds harvested from crossing two inbred (nearly homozygous) parental lines. For example, the female parent is pollinated with pollen of the male parent to produce hybrid (F1) seeds on the female parent.

“Regeneration” refers to the development of a plant from cell culture or tissue culture or vegetative propagation.

“Vegetative propagation,” “vegetative reproduction,” or “clonal propagation” are used interchangeably herein and mean a method of taking a plant part and inducing or allowing that plant part to form at least roots, and also refer to the plant or plantlet obtained by that method. Optionally, the vegetative propagation is grown into a mature plant. The skilled person is aware of what plant parts are suitable for use in the method.

“Crossing” refers to the mating of two parent plants. The term encompasses “cross-pollination” and “selfing”.

“Selfing” refers to self-pollination of a plant, i.e., the transfer of pollen from the anther to the stigma of the same plant.

“Cross-pollination” refers to the fertilization by the union of two gametes from different plants.

As used herein, the terms “resistance” and “tolerance” are used interchangeably to describe plants that show no symptoms or significantly reduced symptoms to a specified biotic pest, pathogen, abiotic influence or environmental condition compared to a susceptible plant. These terms are optionally also used to describe plants showing some symptoms but that are still able to produce marketable product with an acceptable yield.

The term “traditional breeding techniques” encompasses herein crossing, selfing, selection, doubled haploid production, embryo rescue, protoplast fusion, marker assisted selection, mutation breeding etc. as known to the breeder (i.e., methods other than genetic modification/transformation/transgenic methods), by which, for example, a genetically heritable trait can be transferred from one melon line or variety to another.

“Backcrossing” is a traditional breeding technique used to introduce a trait into a plant line or variety. The plant containing the trait is called the donor plant and the plant into which the trait is transferred is called the recurrent parent. An initial cross is made between the donor parent and the recurrent parent to produce a progeny plant. Progeny plants which have the trait are then crossed to the recurrent parent. After several generations of backcrossing and/or selfing the recurrent parent comprises the trait of the donor. The plant generated in this way may be referred to as a “single trait converted plant”. The technique can also be used on a parental line of a hybrid.

“Progeny” as used herein refers to a plant obtained from a plant designated NUN 16108 MEM. A progeny may be obtained by regeneration of cell culture or tissue culture or parts of a plant of said variety or selfing of a plant of said variety or by producing seeds of a plant of said variety. In further aspects, progeny may also encompass plants obtained from crossing of at least one plant of said variety with another melon plant of the same variety or another variety or line, or with wild melon plants. A progeny may comprise a mutation or a transgene. A “first generation progeny” is the progeny directly derived from, obtained from, obtainable from or derivable from the parent plant by, e.g., traditional breeding methods (selfing and/or cross-pollinating) or regeneration (optionally combined with transformation or mutation). Thus, a plant of variety NUN 16108 MEM is the male parent, the female parent or both of a first generation progeny of melon variety NUN 16108 MEM. Progeny may have all the physiological and morphological characteristics of melon variety NUN 16108 MEM, when grown under the same environmental conditions. Using methods such as backcrossing, recurrent selection, mutation or transformation, one or more specific characteristics may be introduced into said variety, to provide or a plant comprising all but 1, 2, or 3 of the morphological and physiological characteristics of melon variety NUN 16108 MEM.

The terms “gene converted” or “conversion plant” or “single locus converted plant” in this context refer to melon plants which are developed by traditional breeding techniques, e.g., backcrossing, or via genetic engineering or through mutation breeding, wherein essentially all of the desired morphological and physiological characteristics of the parent variety or line are recovered, in addition to the one or more characteristics introduced into the parent via e.g., the backcrossing technique (optionally including reverse breeding or reverse synthesis of breeding lines). It is understood that not only the addition of a further characteristic (e.g., addition of gene conferring a further characteristic, such as a disease resistance gene), but also the replacement/modification of an existing characteristic by a different characteristic is encompassed herein (e.g., mutant allele of a gene can modify the phenotype of a characteristic).

Likewise, a “Single Locus Converted (Conversion) Plant” refers to plants developed by plant breeding techniques comprising or consisting of mutation breeding and/or by genetic transformation and/or by traditional breeding techniques, such as backcrossing, wherein essentially all of the desired morphological and physiological characteristics of a melon variety are recovered in addition to the characteristics of the single locus having been transferred into the—variety via above-mentioned technique, or wherein the morphological and physiological characteristic of the variety has been replaced/modified in the variety. In case of a hybrid, the gene may be introduced, or modified, in the male or female parental line.

“Average” refers herein to the arithmetic mean.

The term “mean” refers to the arithmetic mean of several measurements. The skilled person understands that the appearance of a plant depends to some extent on the growing conditions of said plant. Thus, the skilled person understands suitable growing conditions for melon variety NUN 16108 MEM. The mean, if not indicated otherwise within this application, refers to the arithmetic mean of measurements on at least 10 different, randomly selected plants of a variety or line.

In certain aspects, the method comprises: (a) cultivating tissue or cells capable of being propagated from melon variety NUN 16108 MEM, to obtain proliferated shoots; and (b) rooting said proliferated shoots, to obtain rooted plantlets. Steps (a) and (b) may also be reversed, i.e., first cultivating said tissue to obtain roots and then cultivating the tissue to obtain shoots, thereby obtaining rooted plantlets. The rooted plantlets may then be further grown, to obtain plants. In one embodiment, the method further comprises step (c) growing plants from said rooted plantlets. Therefore, the method also comprises regenerating a whole plant from a part of the plant of variety NUN 16108 MEM. In a particular aspect, the part of the plant to be propagated is a cutting, a cell culture or a tissue culture.

The disclosure also provides for a vegetatively propagated plant of variety NUN 16108 MEM, (or from progeny of melon variety NUN 16108 MEM or from a plant having all but one, two or three physiological and/or morphological characteristics of melon variety NUN 16108 MEM), wherein the plant has all of the morphological and physiological characteristics of melon variety NUN 16108 MEM, when the characteristics are determined (e.g., at the 5% significance level) for plants grown under the same conditions. In another aspect, the propagated plant has all but one, two or three of the morphological and physiological characteristics of melon variety NUN 16108 MEM, when the characteristics are determined (e.g., at the 5% significance level) for plants grown under the same conditions.

In another aspect, the disclosure provides a method for producing a melon plant part, such as a fruit, comprising growing a plant of variety NUN 16108 MEM until it sets at least one fruit, and collecting the fruit. Preferably, the fruit is collected at harvest maturity. In another aspect, the fruit is collected when the seed is ripe. In a particular aspect, all fruits on a truss can be harvested together. In another particular aspect, all fruit on a melon plant can be harvested at the same time. A plant of variety NUN 16108 MEM can be produced by seeding directly in the soil (e.g., the field) or by germinating the seeds in a controlled environment (e.g., greenhouses) and optionally then transplanting the seedlings into the field (see, e.g., https://anrcatalog.ucanr.edu/pdf/7209.pdf). For example, a seed is sown into a prepared seed bed in a field where the plant remains for its entire life. Alternatively, the melon seed may be planted through a black plastic mulch. The dark plastic will absorb heat from the sun, warming the soil early. It will also help to conserve moisture during the growing season, controls weeds, and makes harvesting easier and cleaner (see, e.g., https://anrcatalog.ucanr.edu/pdf/7218.pdf). Melon can also be grown entirely in greenhouses.

In still another aspect, the disclosure provides a method of producing a melon plant, comprising crossing a plant of variety NUN 16108 MEM with a second melon plant at least once, allowing seed to develop and optionally harvesting said progeny seed.

Alternatively, the method comprises growing plant of variety NUN 16108 MEM until at least one flower of said variety contains pollen and collecting the pollen. In a particular aspect, the pollen is collected when it is mature or ripe. A suitable method for collecting pollen comprises collecting anthers or the part of the anther that contains pollen, for example, by cutting the anther or the part of the anther off. Pollen can be collected in a container. Optionally, collected pollen can be used to pollinate a melon flower.

The morphological and/or physiological differences between two different individual plants described herein (e.g., between melon variety NUN 16108 MEM and a progeny of said variety) or between a plant of variety NUN 16108 MEM, or progeny of said variety, or a plant having all, or all but 1, 2, or 3, of the physiological and morphological characteristics of melon variety NUN 16108 MEM, and another known variety can easily be established by growing said variety under the same environmental conditions (in the same field, optionally next to each other), preferably repeated in several locations which are suitable for cultivation of melons, and measuring the morphological and physiological characteristics of a representative number of plants (e.g., to calculate an average value and to determine the variation range/uniformity within the variety). For example, trials can be carried out in Acampo Calif., USA (N 38 degrees 07′261″/W 121 degrees 18′ 807″, USA), whereby various characteristics, for example, maturity, days from seeding to harvest, plant habit, plant attitude, leaf shape, leaf color, blistering, numbers of flowers per leaf axil, number of calyx lobes, number of petals, fruit group, immature fruit color, mature fruit color, pungency, flavor, fruit glossiness, fruit size, fruit shape, average number of fruits per plant, seed size, seed weight, anthocyanin level, disease resistance, insect resistance, can be measured and directly compared for species of melon. Thus, the disclosure comprises a melon plant having one, two or three physiological and/or morphological characteristics which are different from those of the plant of variety NUN 16108 MEM, and which otherwise has all the physiological and morphological characteristics of said variety, when determined (e.g., at the 5% significance level for quantitative characteristics or determined by type for non-quantitative characteristics) for plants grown under the same environmental conditions. In another aspect, the different characteristic is affected by a mutation, optionally induced mutation, or by transformation.

The morphological and physiological characteristics of melon variety NUN 16108 MEM are provided, for example, in Tables 1 and 2, as collected in a trial according to USDA and/or UPOV standards. Encompassed herein is also a plant obtainable from melon variety NUN 16108 MEM, (e.g., by selfing and/or crossing and/or backcrossing with said variety and/or progeny of said variety) comprising all or all but one, two or three of the physiological and morphological characteristics of melon variety NUN 16108 MEM listed in Tables 1 and 2 (as determined at the 5% significance level for numerical characteristics or identical for non-numerical characteristics) when grown under the same environmental conditions and/or comprising one or more (or all; or all except one, two or three) characteristics when grown under the same environmental conditions. The morphological and/or physiological characteristics may vary somewhat with variation in the environment (e.g., temperature, light intensity, day length, humidity, soil, fertilizer use, disease vectors), which is why a comparison under the same environmental conditions is preferred. Colors can best be measured using the Royal Horticultural Society (RHS) Chart.

Also, at-harvest and/or post-harvest characteristics of fruits can be compared, such as cold storage holding quality, post-harvest flesh firmness, and Brix can be measured using known methods. (Fruit) Flesh firmness can, for example, be measured using a penetrometer, e.g., by inserting a probe into the fruit flesh and determining the insertion force, or by other methods. Fruit flesh firmness can for example be measured using a “FT 327 Penetrometer”, available from QA Supplies LLC, 1185 Pineridge Road, Norfolk, Va. 23502.

The disclosure provides for methods of producing a plant which retain all the morphological and physiological characteristics of a plant described herein. The disclosure also provides for methods of producing a plant comprising all but 1, 2, 3 or more of the morphological and physiological characteristics of melon variety NUN 16108 MEM (e.g., as listed in Tables 1 and 2), but which are still genetically closely related to said variety. The relatedness can, for example, be determined by fingerprinting techniques (e.g., making use of isozyme markers and/or molecular markers such as Single-nucleotide polymorphism (SNP) markers, amplified fragment length polymorphism (AFLP) markers, microsatellites, minisatellites, Random Amplified Polymorphic DNA (RAPD) markers, restriction fragment length polymorphism (RFLP) markers and others). A plant is “closely related” to melon variety NUN 16108 MEM, if its DNA fingerprint is at least 80%, 90%, 95% or 98% identical to the fingerprint of melon variety NUN 16108 MEM. In a particular aspect, AFLP markers are used for DNA fingerprinting (see, e.g., Vos et al. 1995, Nucleic Acid Research 23: 4407-4414). A closely related plant may have a Jaccard's Similarity index of at least about 0.8, preferably at least about 0.9, 0.95, 0.98 or more (see, e.g., Parvathaneni et al., J. Crop Sci. Biotech. 2011 (March) 14 (1): 39-43). The disclosure also provides a plant obtained or selected by applying these methods on melon variety NUN 16108 MEM. Such a plant may be produced by traditional breeding techniques, or mutation or transformation or in another aspect, a plant may simply be identified and selected amongst plants of said variety, or progeny of said variety, e.g., by identifying a variant of melon variety NUN 16108 MEM, which variant differs from the variety described herein in one, two or three of the morphological and/or physiological characteristics (e.g., characteristics listed in Tables 1 and 2). In one aspect, the disclosure provides a plant of variety NUN 16108 MEM, having a Jaccard's Similarity index with said variety of at least 0.8, e.g., at least 0.85, 0.9, 0.95, 0.98 or even at least 0.99.

In some aspects, the disclosure provides a melon plant comprising genomic DNA having at least 95%, 96%, 97%, 98% or 99% sequence identity compared to the genomic DNA sequence of a plant of variety NUN 16108 MEM as to be deposited under Accession Number NCIMB 43406. In some aspects, the melon plant further comprises all or all but 1, 2, or 3 of the morphological and physiological characteristics of melon variety NUN 16108 MEM (e.g., as listed in Tables 1 and 2). In other aspects, the melon plant is a hybrid derived from a seed or plant of variety NUN 16108 MEM.

For the purpose of this disclosure, the “sequence identity” of nucleotide sequences, expressed as a percentage, refers to the number of positions in the two optimally aligned sequences which have identical residues (×100) divided by the number of positions compared. A gap, i.e., a position in the pairwise alignment where a residue is present in one sequence but not in the other, is regarded as a position with non-identical residues. A pairwise global sequence alignment of two nucleotide sequences is found by aligning the two sequences over the entire length according to the Needleman and Wunsch global alignment algorithm described in Needleman and Wunsch, 1970, J. Mol. Biol. 48(3):443-53). A full implementation of the Needleman-Wunsch global alignment algorithm is found in the needle program in The European Molecular Biology Open Software Suite (see, e.g., EMBOSS, Rice et al., Trends in Genetics June 2000, vol. 16, No. 6. pp. 276-277).

The disclosure also provides methods for determining the identity of parental lines of plants described herein, in particular the identity of the female line. US2015/0126380, which is hereby incorporated by reference, relates to a non-destructive method for analyzing maternal DNA of a seed. In this method, the DNA is dislodged from the seed coat surface and can be used to collect information on the genome of the maternal parent of the seed. This method for analyzing maternal DNA of a seed comprises contacting a seed with a fluid to dislodge DNA from the seed coat surface, and analyzing the DNA thus dislodged from the seed coat surface using methods known in the art. The skilled person is thus able to determine whether a seed has grown on a plant of a plant of variety NUN 16108 MEM, or is a progeny of said variety, because the seed coat of the seed is a maternal tissue genetically identical to melon variety NUN 16108 MEM. In one aspect, the disclosure relates to a maternal tissue of melon variety NUN 16108 MEM. In another aspect, the disclosure relates to a melon seed comprising a maternal tissue of melon variety NUN 16108 MEM. In another particular aspect, the disclosure provides a method of identifying the female parental line of melon variety NUN 16108 MEM by analyzing the seed coat of a seed of that variety. In another aspect, the skilled person can determine whether a seed is grown on melon variety NUN 16108 MEM, by analyzing the seed coat or another maternal tissue of said seed.

By crossing and/or selfing (one or more) single traits may be introduced into melon variety NUN 16108 MEM (e.g., using backcrossing breeding schemes), while retaining the remaining morphological and physiological characteristics of said variety and/or while retaining one or more or all distinguishing characteristics. A single trait converted plant may thereby be produced. For example, disease resistance genes may be introduced, genes responsible for one or more quality traits, yield, etc. Both single genes (e.g., dominant or recessive) and one or more QTLs (quantitative trait loci) may be transferred into melon variety NUN 16108 MEM by breeding with said variety.

In one aspect, the disclosure provides a haploid plant and/or a doubled haploid plant of melon variety NUN 16108 MEM, or a plant having all but one, two or three physiological and/or morphological characteristics of melon variety NUN 16108 MEM, or progeny of any of these. Haploid and doubled haploid (DH) plants can, for example, be produced by cell or tissue culture and chromosome doubling agents and regeneration into a whole plant. DH production chromosome doubling may be induced using known methods, such as colchicine treatment or the like. In one aspect, the method comprises inducing a cell or tissue culture with a chromosome doubling agent and regenerating the cells or tissues into a whole plant.

In another aspect, the disclosure comprises a method for making doubled haploid cells from haploid cells of melon variety NUN 16108 MEM, comprising doubling cells of said variety with a chromosome doubling agent such as colchicine treatment (see, e.g., Nikolova and Niemirowicz-Szczytt (1996) Acta Soc Bot Pol 65:311-317).

In another aspect, the disclosure provides for haploid plants and/or doubled haploid plants derived from melon variety NUN 16108 MEM that, when combined, make a set of parents of melon variety NUN 16108 MEM. The haploid plant and/or the doubled haploid plant of variety NUN 16108 MEM can be used in a method for generating parental lines of melon variety NUN 16108 MEM.

Using methods known in the art such as “reverse synthesis of breeding lines” or “reverse breeding”, it is possible to produce parental lines for a hybrid plant such as melon variety NUN 16108 MEM. A skilled person can take any individual heterozygous plant (called a “phenotypically superior plant” in Example 2 of US2015/0245570 hereby incorporated by reference in its entirety; melon variety NUN 16108 MEM is such plant) and generate a combination of parental lines (reverse breeding parental lines) that, when crossed, produce the variety NUN 16108 MEM. It is not necessary that the reverse breeding parental lines are identical to the original parental lines. Such new breeding methods are based on the segregation of individual alleles in the spores produced by a desired plant and/or in the progeny derived from the self-pollination of that desired plant, and on the subsequent identification of suitable progeny plants in one generation, or in a limited number of inbred cycles. Such a method is known from US2015/0245570 or from Wijnker et al., Nature Protocols Volume: 9, Pages: 761-772 (2014) DOI: doi:10.1038/nprot.2014.049.
